The settings and procedures described in published studies focused on assessing and treating pica may not be relatable or feasible for all practitioners. This brief report demonstrates a successful replication of modified methods for assessing and treating a 16-year-old diagnosed with Autism Spectrum Disorder who engaged in pica. The study extended the existing research on pica in the following ways: First, it supported the utility of brief analysis methods, including brief functional analysis (FA) sessions, fewer FA sessions, and a preference assessment requiring less time to complete. Second, it described an FA for pica in a home setting. Finally, it evaluated the utility of differential reinforcement of alternative behavior in the form of mands in treating pica.

异食癖的简要评估

已发表的研究中描述的以评估和治疗异食癖为重点的设置和程序可能并非对所有从业者都具有相关性或可行性。这份简短的报告展示了一种改进的方法的成功复制，用于评估和治疗一名 16 岁被诊断患有自闭症谱系障碍并从事异食癖的儿童。该研究通过以下方式扩展了现有的异食癖研究：首先，它支持使用简短的分析方法，包括简短的功能分析 (FA) 会话、更少的 FA 会话以及需要更少时间完成的偏好评估。其次，它描述了家庭环境中异食癖的 FA。最后，它评估了在治疗异食癖中以要求的形式对替代行为进行差异强化的效用。
